The moth, which is captured in the trap

Damage: the larvae mine in the leaves producing smaller orlarger galleries through feeding on the mesophyll tissues.They can also burrow into the fruit, causing a substantial lossof tomato production in greenhouses and also in the field.Damage can reach up to 100%. Damages can occurthroughout the entire growing cycle of tomatoes.Tomato plants can be attacked from seedlings to matureplants. In tomato damage can take place on apical buds,leaves, stems, flowers and fruits, on which the black frass isvisible. On potato, mainly the green parts are attacked.Recently damage on tubers was also reported.The pheromone trap should be suspended at the level of thetop of vegetation. Expected beginning of trapping in Hungaryis beginning of April.

Selectivity of the CSALOMON® trap: so far no other specieshas been reported.

Longevity of the CSALOMON® trap in field conditions: depending on the warmth of the weather at least 4-6weeks. After this period we suggest to set up a new trap for most effective detection and monitoring. Renewal ofsticky inserts in intervals of 7-10 days. In case of high catches this may become necessary more often.

Pheromone traps are ideal for the detection of the presence of Tuta absoluta. Monitoring of the flight patternand the timely detection of a mass outbreak can also be performed. Control measures are most efficient ifapplied against the young larvae. In hot weather several generations can develop, which can grow in numbersespecially in the second half of the summer.

Tuta absoluta originates from South America, where it became a serious pest from the 1980-s. In the Old World,since the first detection in Spain in 2006, the pest is spreading rapidly across SouthernEurope and North Africa in the Mediterranean countries. Its presence has been reported in Italy, France, Malta,United Kingdom, Greece, Switzerland, Portugal, Morocco, Algeria, Tunisia, Libya and Albania [1]. Until 2009, ithas not been detected in Hungary.
